RAILWAY SIGNALING APPARATUS.

'SPECIFICATION forming part of Letters Patent No. 260,713, dated July 4, 1882.

v Application filed February 23, 1882. (No model.) Patented in England May 25, 1881, No. 2,297.

To all whom it may concern:

Be it known that we, ROBERT ALFRED STANLEY and ROBERT STANLEY, subjects of the Queen ot' Great Britain, residing at Manchester, in the county of Lancaster, England, have jointly invented a new and useful Im provemeut in Railway Signaling Apparatus,

(for which we have obtained a patent in Great' to an alarm or recording apparatus at a distance with facility, to attest its working and the condition of. the line, as hereinafter described and claimed.

Figure 1 of the accompanying drawings represents a side elevation ot' two more or less widely separated portions of a railway-track provided with an improved signaling apparatus. Fig. 2 represents a plan view of the same with the semaphore-post in section. Fig. 3 represents a transverse section ot' the track, showin g aside view of the semaphore and adjacent parts; and Fig. 4 represents a view of the latter from the same direction as Fig. l, with the rails removed to expose the signaling mech anism-like letters ot reference indicating corresponding parts in the several tgures.

In carrying out our invention we employ a main lever, A, mounted at right angles to the rails B, said main -lever having a short end which passes under the near rail, and is so formed that its extremity O projects slightly above the rail and close thereto, presenting a long curved surface to the lian ges of the wheels of trains of cars passing over it. The other or longer arm of said main lever is jointed or linked to the shorter arm ot' a second lever, l), which is mounted parallel to the line ot' rails, and immediately alongsidea semaphore signalpost, E; A rod or wire, F, connects the longer arm of said second lever with the semaphorearm, G, which is pivoted, as shown in Fig. 3, so as to be elevated by pulls on said rod or Wire. Said long arm ofthe second lever is provided with a weight, w, secured thereon in proper position to counterbalance the semaphore-arm, so that it will remain in itsrespective positions without the aid of detents. At the same time a flexible wire is sufficient for 6o the connection F, as gravity tends to return the semaphore-arm to itslower position, (indicated by full lines in Fig. 3,) and it is drawn to its elevated position (indicated by dotted lines in Fig. 3) by pulls, as aforesaid. Another wire, 65 H, connected to the opposite end of said second lever, passes downward, and, being carried partly around a grooved deileeting-pulley, I, extends along the line of rails to the next station ahead, and is there connected to a bell, 7o (not shown,) for which any suitable alarm or recording apparatus may be substituted. A simple bell serves to give sonorous indication otl the working of the apparatus, so that iuoperativcness through the failure ot' any part 75 can be immediately detected and remedied. On its way to the station said wire H passes under another pulley, J, Fig. 2, similar to I, and is connected to the extremity of the longer arm of a resetting-lever, K, similar to the main 8o lever A, so as to elevate the head L of said resetting-lever when that ot the main lever is depressed. From said resetting-lever said wire H passes under another pulley, M, Fig. 2, and l thence direct to the station, the signaling ap- 8 5 paratus of each block-section of the road being separately connected with the station or stations ahead. y

Theoperation of this apparatus is asfollows: Assuming that the tlange or head G of the 9o main lever A is in its elevated position and that the arm G ot' the semaphore-post E is down, as shown in full lines in Fig. 3, which indicates that the guarded section is unoccupied or open, the first wheel of an approaching train on the near rail ot' the tra-ck B will actuate said main lever by depressing said flange or head O, thus elevating the long end of said main lever and .the short end of the secondlever,D, depressing the long end of said Io second lever and pulling the connecting rod or wire F, so as to raise the semaphore-arm to its elevated position, in which it is shown in dotted lines in Fig. 3, as aforesaid, thus rendering the track blocked/7 and at the same time, through the wire H, indicating or recording this act at the station. The succeeding car-wheels, acting on said flange or head C, keep the semaphore-arm in its elevated position against any tendencyofthe jar of the train to displace it until the last car passes, andthe counter-balance w adapts the semaphorearm to maintain the same position until it is lowered by the action of the resetting-lever K, through said wire H, lever D, and connecting rod or wire F, when the ange of said first wheel of the train strikes the head L of said lever K. The latter, lei't by the train in depressed position, is re-elevated by the next depression ofthe head ofthemainleverth rough the medium of said wire H, and thus the operation proceeds automatically and without the aid of springs or other complications.

Having thus described our invention, we would have it; understood that we do not claim a semaphore-signal operated by the wheels ot' passing trains through levers and connecting z5 media, broadly considered.

We claim as new and of our own inventionlhe.comhination, in a block signaling apparatusfor railways, ofa main lever, A, mounted at right angles to the track, and constructed 3o with a head, G, adapted to coactwith the wheels of passing trains, a second lever, D, parallel to the track, adapted to transmit pulling impulses f rom said main lever, and provided with a counter-weight. a connecting rod or Wire, F, 35 transmitting said impulses to a pivoted semaphorearm, G, a wire, H, leading from said second lever to a station ahead, a resettinglever, K, similar to said main lever, and delecting-pullcys to coact with said wire H, as 4o and for the purpose hereinbefore described and illustrated on the accompanying drawings.
